After that, the discharge means is operated, so that the boiling maintenance time after boiling can be minimized, and furthermore, when the discharge means is operated to discharge hot water, it is determined by the circulation means even while the circulation means is operating. Was Can be ejected in any way affected by that rate preferences set from the beginning without the amount, can improve the usability.

Is activated, and thereafter the discharge means is stopped, it is possible to prevent an accident such as a burn due to the unexpected flow of the flow rate determined by the circulation means immediately before the end of the operation of the discharge means, thereby improving safety.
